CLOSURE FOR GAS-PURIFIERS.

Specification of Letters Patent.

Application filed December a, 1912. Serial No. 735,202.

Patented Sept. 16, 1913.

To aZZ whom it may concern: a 1

Be it known that I, ERNns'rF. LLOYD, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented cerand at the same time to afford ample drainagefor water or melting snow and ice.

This invention relates to a closure for gas purifiers tanks or the likeand more particularly to an arrangement thereof which insures resistanceagainst any internal pressure and ready drainage of theclosureregardless of weather conditions, and tightly seals the receptacles.

The invention consists in the matters hereinafter set forth and pointedout in the claims.

In the drawings, Figure 1 is a plan view of a portion of a closure for agas purifier or tank that embodies features of the invention; Fig. 2 isa view in side elevation thereof; Fig. 3 is a view in detail of thefastening and scupper draining arrangement; and Fig. 1 is a view indetail'of the soupper and clamping means.

As herein shown a purifier or tank of preferred form and dimensions,preferably made of masonry or cement, has a curb wall 1 that may beprovided with a plate 2, and from which anchor bolts 3 extend upwardly.A closure that conforms substantially to the tank, is made of a deck 4of sheet metal or the like that is supported at its margins on theinwardly projecting flanges 5 of depending side and end plates 6 thelatter forming an unbroken flange around the deck. An'angle bar 7 on theoutslde of each of the latter co acts with a clamping strip 8 and bolts9 or like holding means to retain a gasket 10 of suitable yieldingmaterial that rests on the curb 1 or curb plate 2. The closure sheet 4:is slightly cambered or crowned and is reinforced by correspondinglybent channels or I-beams 11 at regular intervals, whose end portionsproject slightly beyondthe side plates 6 and carry channel clampingbeams 12. The latter are .secured to the ends of the beams 11 by bracketangles 13. Plates 1d at regular intervals together with the ends of thebeams 11 act as spacers to maintain the members 12 at an interval fromthe plate 6, the spacers 14 being secured by suitable means to theinside of the member 12 and the outside of the plates 6. Holding plates18 are secured on the upper flanges of the end portions ofthe beams 11and extend over the members 12. Suitable bolts 15 anchored in anypreferred manner to the curb 1, engage these holding plates, the flanges16 of the channels 12 being notched to clear the bolts. Gross beams 17of appropriate dimensions and arrangement are used to stiffen thestructure at the end portions of the closure, and as indicated in Fig.1, form supports for the clamping plates 14. Asa result of thisarrangement of parts a closure is obtained that is readily securedfirmly to the curb of a purifier or tank of large dimensions in such away as to hermetically seal the latter. The arrangement of beams andclamping members stiffens the structure against internal pressure whilethe placing of the side members at an interval from the deck of theclosure leaves scupper spaces from which melted snow, and ice readilydrain.

Obviously, changes in the details of construction may be made withoutdeparting fromthe spirit of my invention and I do not care to limitmyself to any particular form or arrangement of parts.

l/Vhat I claim is 1. The combination with a receptacle'having anchorbolts, of a closure thereforhaving a crowned deck, depending side andend plates, a gasket projecting below the margin of the side and endplates, and supporting the closure on the tank, clamping beams securedaround the closure at an in terval from the deck, and holding members onthe beams engaged by the bolts.

2. The combination with a receptacle having a curb and anchor bolts, ofa closure having a crowned deck, depending side and end plates forming acontinuous flange for the deck, transverse beams on the deck, clampingbeams secured on the ends of the beams, spacing plates secured to theinside of the clamping beams and the outside of the side plates wherebythe clamping beams are at an interval from the deck, a gasket projectingbelow the margins of the side and end plates and resting on the curb,and holding plates engaged'by the anchor bo ts. 8. The combination withthe curb of a gas purifier, of a closure therefor consisting 5 of a.crowned deck, having side and end plates that form an unbroken flangearound the deck, a yielding gasket on the flange supporting the closureon the curb,.stifiening' h members across the deck clamping beams /'10around. the deck, spacers securing the latter bolts on the curb engagingto the deck flange to form scupperspacc's, holding plates on theclosure, and anchor the holding plates. r

In testimony whereof I affix my signature 15 in presence of tWoWitnesses.
